Running Multiple Instances on One Tomcat server

0
Stuart Brown (33●10●9) | asked Apr 30 '08, 11:56 a.m.
Hello
Just wondering if its possible to run multiple instances of RTC under one instalation of Tomcat ?

Currently Im running 3 instances, however each of these is under a different install area on the same server using different ports.

Has anyone done this so far ?

Thanks

Stu

From my understanding (Community please correct me if I am wrong), each

repository of Jazz needs to be on a separate JVM in order to inherit the
appropriate TeamConcert.properties. Since your main concern is
different ports, You may want to consider using multiple WAS instances
with the IHS Plug-in. My team has been successful with that configuration.

Thanks for the reply.

If using WAS is the only way we can do this, thats what we will do.

Thanks again for your advise

Hi all,
we do use multiple instances of WAS for multiple instances of Jazz.
We were also able to deploy multiple different of Jazz in that setting.
Just make sure that during the IHS plug-in generation each WAS profile doesn't overwrite the setting of the others: we created manually a WAS IHS plug-in file to include adequately our three WAS instances (or profiles).
We do overwrite the plug-in cfg file after each deployment.
cheers!

Would like to check something please

We are able to run multiple instances of RTC, each on its own instance of tomcat.
We are unable to run multiple instances of RTC on the same tomcat server
From the reply it mentioned that you can/should run multiple instances of WAS, are we saying then that each RTC instance needs to have its own WAS instance ? if so equivalent to the current setup I have of having multiple instances of Tomcat ?
What I'm asking if we can deploy the RTC application more than once in the same WAS instance, each pointing to separate repositories using different teamster files.

Also the IHS plug in, is this only needed if you want to run a separate web server ?

Apologies for sounding vague, not familiar with WAS, gonna have to do some reading if this is the way to go

Thanks

Stuart, today, you CANNOT run multiple Jazz instances in one Tomcat or WAS instance, you would need three separate instances. As Aaron said above, this is due to the system property which points to the teamserver.properties configuration for a Jazz server. Each Jazz instance would try to use the same db connection.

Aaron and others, it would be great if you could post more detailed instructions for successfully setting up Jazz with multiple WAS instances.

Thanks,
Scott Rich
